Everything you need to know about the Canadian Investment Regulatory Organization (CIRO): a dynamic resource

Welcome to BLG and BLG Beyond AUM Law’s dynamic resource on the Canadian Investment Regulatory Organization (CIRO). We invite you to bookmark and revisit this page which will be updated to reflect developments of importance to CIRO registered firms. Resulting from the amalgamation of the Investment Industry Regulatory Organization of Canada (IIROC) and the Mutual Fund Dealers Association of Canada (MFDA), CIRO has been operating since January 1, 2023 and has led to – and will continue to generate – significant changes in the registration and oversight of investment and mutual fund dealers across Canada, as well as new opportunities. This resource is designed to help you find, understand and act on CIRO-related topics, such as new developments, rules, registration requirements, enforcement and examinations and more.
